Your Data Center's DNS Zone Check
performs several tests on your zone (ie:domain) to ensure that it is
correctlyconfigured and can be safely delegated, providing a certain
quality to your domain (see the benefit section).

For detailed information on how to fill
this form see the
help section.

The time required to completely verify a zone can take
from 10 seconds up to 5 minutes depending on the network
speed of the server being accessed.
If execution takes more than a minute it generally means
slow access to your nameservers (configuration error, firewall, ...)
is occurring. Expect a timeout.
